We deyeloped a simple screening method for antioxidant-producing strains using 1,1-diphenyl-2picrylhydrazyl (DPPH) and screened bacteria from 16 kinds of marine animals that lived in different enyironments in the sea to find 112 bacterial iso]ates producing antioxidants. Guided by decoloration of DPPH sprayed on silica gel TLC, uric acid, indole, 3,4-dimethoxyphenol, and 3-hydroxyindolin-2-one ...

Abstract Purpose Balanophora polyandra Griff. is a holoparasitic medicinal plant that produces compounds with antibacterial and antioxidant activities. Plant endophytic fungi are an abundant reservoir of bioactive metabolites for exploitation, increasing number novel being isolated from fungi. The present study investigated the diversity culturable roots holoparasite B. to explore active strain...

INTRODUCTION Reactive oxygen and nitrogen free radicals are produced during immune activity, and are triggered by several environmental factors such as pollution, smoke, and sunlight. Harmful effects of these reactive species include cellular damage to RNA, DNA, proteins and lipids. In humans several diseases including those connected with the heart, lung, and the eye are associated with the ac...

In this study antimicrobial effects of Salivia mirzayanii and Saliva atropatana were evaluated against six gram-positive and gram-negative bacteria by immersion bioautography, cylinder plate and tube dilution methods separately. In bioautography method, essential oils of Salvia mirzayanii and Salvia atropatana were separated on silicagel TLC plates by toluene-ethyl acetate (93-7). In cylander p...

Decoction and 75% ethanolic extracts from the leaves of Acanthopanax trifoliatus (AT) and Toddalia asiatica (TA) were spectrophotometrically examined for antioxidant activity and phenolics content. Phytochemical characteristics of the decoction extracts were also investigated by thin layer chromatography (TLC). The leaf decoction extract of AT significantly exhibited the highest in vitro antiox...

A combination of TLC-bioautography, MALDI-TOF-MS, and LC-MS/MS methods was used to identify flavonoids with anti-α-amylase activity in extracts L. pratensis (herb), polyphillus (fruits), T. lanceolata R. Br. S. japonica (buds). After TLC-autobiography assay, substances anti-amylase were identified by MALDI-TOF-MS followed confirmation the result LC-MS/MS. Results study revealed that apigenin, l...

Bajakah wood (Spatholobus Littoralisk Hask) is empirically used by the community to treat stomach pain, diarrhea and even believed be able cancer. Several studies have shown its activity as an antibacterial. The purpose of this study was identify compounds with antibacterial properties using Gas Chromatography Mass Spectroscopy (GCMS). method in research experimental method. plants were obtaine...

The increasing occumnce of opportunistic systemic mycoses associated with the use of immunosuppressive drugs and AIDS has led to new efforts in the search for novel antifungal compounds. At the same time, there is continuing interest in the discovery of antifungal agents which are effective against plant pathogenic fungi. Since the plant kingdom provides a useful source of lead compounds of nov...
